Ndezvipi zvinhu zvikuru zveRoller Reamer Cutter uye divi rayo?

Pakugadzira, kusarudza, kana kutengaRoller ReamerMucheka, zvinhu uye saizi zvinhu zvakakosha zvinokanganisa mashandiro ayo, hupenyu hwayo, uye mashandisirwo ayo. Heano zvinhu zvakakosha zvekufunga nezvazvo:

1. Zvaunofanira Kufunga Nezvekusarudza Zvinhu

Zvinhu zvikuru zvinopfekwa neRoller Reamer Cutter zvinosanganisira maroller cutters nemuviri. Sarudzo yezvinhu inofanira kuenderana nekuomarara, kuramba kupfeka, kusimba kwemuchina wekupwanya, uye kuramba kupisa kwakanyanya.

(1) Zvinhu zvekucheka maroller

-Tungsten Carbide (WC)

- Sarudzo inonyanya kuzivikanwa, inopa kuomarara kwakanyanya (HRA 90+) uye kuramba kupfeka.

- Yakakodzera kuvakwa kwepakati nepakati kusvika kune kwakaoma zvakanyanya (semuenzaniso, granite, quartzite).

- Cherechedza huwandu hwe cobalt (Co) (6% ~ 15%)—cobalt yakawanda inovandudza kusimba asi inoderedza kuomarara.

- PDC (Polycrystalline Diamond Compact)

- Yakakodzera kugadzirwa kwakapfava kusvika pakati nepakati, ine simba rakanaka rekudzivirira kupfekwa asi isingakuvadzi zvakanyanya.

- Inoshandiswa zvakanyanya mukuchera mafuta uye kuongorora geology.

- Mapeti eCeramic kana Ultra-Hard (semuenzaniso, TiN, DLC)

- Inoshandiswa munzvimbo dzinopisa zvakanyanya asi pamutengo wakakwira.

(2) Zvinhu zvemuviri

- Simbi yeAlloy (semuenzaniso, 4140, 4340)

- Inoda kurapwa kwekupisa nekudzimisa (QT) kuti iwedzere kusimba uye kusimba.

- Simbi Isina Kushanda (semuenzaniso, 17-4PH)

- Inoshandiswa munzvimbo dzinopisa (semuenzaniso, kuchera matombo ari kunze kwegungwa, kuumbwa kweasidhi).

- Kurapa pamusoro (semuenzaniso, kuisa chrome plating, kuisa nitriding) kunogona kuwedzera kuramba kweganda richiramba kupera.

Pfungwa huru dzekusarudza zvinhu:

✅ Sarudza chinhu chinocheka maroller zvichienderana nekuomarara kwekugadzirwa (dombo rakaoma → tungsten carbide, dombo rakapfava → PDC).

✅ Funga nezvezvinhu zvinokanganisa ganda kuti risatsemuke uye risatsemuke.

✅ Panzvimbo dzine ngura (semuenzaniso, mvura yemunyu, H₂S), shandisa simbi isina ngura kana machira akakosha.

2. Zvaunofanira Kufunga Nezvehukuru

Kukura kweRoller Reamer Cutter kunokanganisa zvakananga kuenderana kwayo nedhayamita yeborehole, kugadzikana, uye kushanda zvakanaka kwekucheka.

(1) Dhayamita Yekunze (OD)

- Inofanira kuenderana nedhayamita yeborehole (kazhinji yakakura zvishoma pane drill bit yekugadzirisa maburi).

- Funga nezve ma tolerances (± 0.1~0.5mm) kuti uve nechokwadi chekuti reaming yacho yakarurama.

- Mukuchera mafuta, munofanira kutevedzera mitemo yeAPI (semuenzaniso, API 7-1).

(2) Kureba

- Zvinokanganisa kugadzikana—zvinoita kuti madziro arambe akareba zvinopa nhungamiro iri nani asi zvinogona kuwedzera kukweshana.

- Hurefu hwenzvimbo: 200mm ~ 1500mm (zvichienderana nekushandiswa).

(3) Nhamba uye Kurongeka kweVatemi

- Zvigayo zvekucheka zvinosvika 3~6 ndizvo zvinonyanya kuwanikwa—zvigayo zvakawanda zvinowedzera kugadzikana asi zvinowedzera kudiwa kwesimba.

- Kurongeka kwesimbi inotenderera kunoderedza kudedera, kwakakodzera kucherwa maburi akadzika.

(4) Rudzi rwekubatanidza (Thread)

- Mashinda eAPI (semuenzaniso, NC50, 6 5/8″ REG) ekushandisa pakuboorera mafuta.

- Zvinobatanidzwa zvakakosha (semuenzaniso, IF, FH) zvinofanira kuenderana netambo yekuboorera.

Pfungwa dzeKusarudza Dimension Yakakosha:

✅ OD inofanira kuenderana nehukuru hwechibhorani chakatarwa, zvichireva kusakara nekufamba kwenguva.

✅ Kureba-kusvika-dhayamita (L/D) kunokanganisa kugadzikana—maremu marefu akanakira maburi akadzika.

✅ Kubatanidza shinda kunofanirwa kuenderana netambo yekuboorera kuti zvisakanganise maburi.

3. Zvimwe Zvikamu Zvakakosha

- RPM yepamusoro:Zvinokanganisa hupenyu hwemuchina wekucheka—zvinofanira kuiswa zvichienderana nezvinhu zvakagadzirwa uye mafuta ekuzora.

-Kupisa Kunoshanda:Nzvimbo dzinopisa zvakanyanya (semuenzaniso, matsime akadzika) dzinoda ma alloys asingapisi.

- Kuenderana kweMadhaka/Zvinotonhodza: Iva nechokwadi chekuti zvinhu zvinodzivirira ngura kubva muzvinwiwa zvinoboorwa.

Pfupiso: Rondedzero Yekusarudza

|Chinhu | Zvaunofanira Kufunga |

|————–|————|

| Zvinhu zveKucheka Roller | Tungsten carbide (dombo rakaoma), PDC (dombo rakapfava), kuramba kukanganiswa |
